Packaged engine working machine

Abstract

There is provided a packaged engine working machine including, in a lower space of a package an electrical component storage box adapted to be impervious to heat from the engine and intrusion of dust or the like. In a packaged engine working machine in which an engine and a working machine driven by the engine are disposed in a lower space of a package, a storage box for storing a non-heat-generating electrical component included in electrical components for the engine and working machine, and a ventilation duct having a ventilation fan for sucking outside air into the lower space are each disposed in the lower space, and the packaged engine working machine includes an introduction path through which the ventilation duct and the storage box are communicated with each other, and the outside air sucked by the ventilation fan is partially guided into the storage box.

The invention claimed is: 
     
       1. A packaged engine working machine in which an engine and a working machine driven by the engine are disposed in a lower space of a package,
 wherein a storage box for storing a non-heat-generating electrical component included in electrical components for the engine and working machine, and a ventilation duct comprising a ventilation fan for sucking outside air into the lower space are each disposed in the lower space, and 
 wherein an inner space of the storage box is hermetically sealed by interposing a sealing member for gaps of a plurality of internal wiring holes, a plurality of external wiring holes and various screw attachment holes provided in wall surfaces constituting the storage box, and the storage box and the ventilation duct are connected to each other by interposing a hermetical seal between the storage box and a communication pipe which connects the storage box with the ventilation duct, thus allowing the lower space and the inner space of the storage box to have equal positive pressure. 
 
     
     
       2. The packaged engine working machine according to  claim 1 ,
 wherein an underfloor space provided below the lower space comprises: an upper floor plate provided with a plurality of vent holes; and a lower floor plate disposed in parallel with the upper floor plate at a distance therefrom. 
 
     
     
       3. The packaged engine working machine according to  claim 1 ,
 wherein the non-heat-generating electrical component is at least one of a terminal block, a relay, a fuse and a breaker.
